Of course, something like that will only happen if they able to remove the dissonance between their brainwaves that usually gives them migraines so bad they end up catatonic.
That will only happen if they fall in ~looooooooooove~ and achieve perfect harmony. Wait...this isn't Macross 7.

All kidding aside, we do know from flashbacks that Marie and Al used to communicate fully telepathically using the quantum brainwaves, and everything was peachy between the two.

Since they both developed alternate personalities, Allelujah would get the migraines from Soma and Soma would get them from Allelujah, but worse from Hallelujah. It doesn't seem like she uses the shielding anymore, and now that Allelujah has lost the quantum brainwaves, he doesn't have the problems either, though Soma can still sense that it is him. Something changed in her head when Marie became Soma.
